FLASK.

SPECIFICATION forming part of Letters Patent No. 510,172, dated December5, 1893.

Application filed June 12, 1893. Serial No. 477,278. (No model.)

To a. whom it may concern:

Be it known that I, HENRY J. GRAF, of East St. Louis, St. Clair county,State of Illinois, have invented certain new and useful Improvements inFlasks, of which the following is a full, clear, and exact description,reference being had to the accompanying drawings, forming a part hereof.

My invention relates to improvements in flasks or more specificallyflask clamps and consists in the novel arrangement and combination ofparts as will be more fully hereinafter described and designated in theclaims.

The object of my invention is to provide certain improvements so as toenable flasks suchas are commonly used in foundries to becomeinterchangeable and also to provide a flask clamp that is adjustable,detachable and portable, thus obviating breakage and repairage.

I will give a further description of the objeot of my invention inconnection with a mechanical description thereof.

In the drawings: Figure 1 is a longitudinal vertical mid-section takenthrough the parts of the flask,that is the upper part or the cope andthe lower part or the drag and also through the clamps which are securedto the ends of said parts, Fig. 2 is a detail perspective view of thedetachable ear which is secured to the cope. Fig. 3 is a detailperspective view of the detachable ear which is secured to the drag.Fig. 4 is a detail perspective view of a detachable clamp which isnormally mounted on the ear as illustrated in Fig. 3.

Referring to the drawings: 1 indicates the upper part or cope of theflask, and 2 indicates the lower part or drag of the flask, it beingnoted in this connection that the description herein relates to what iscommonly known as a two-part flask.

As the clamping mechanism, or more specifically the cars which aresecured to the ends of the cope are the same I will only give adescription of one, and furthermore as the ears'which are secured to theends of the lower part or drag of the flask are the same, I will onlygive a description of one.

3 indicates the ends of the cope and secured to the lower externalportion of said ends are detachable ears 4. Said ears are providedrectangular depression.

with perforations or apertures 5, through which screws or bolts 6 may beinserted for the purpose of securing said ears to the ends 3. Said .ears4 are provided with an approximately U-shaped depression 7 for thepurpose more fully hereinafter described, and also with strengtheningribs or webs 8 so as to increase the strength and stability of said earsin a manner apparent.

9 indicates detachable cars which are detachably secured to the upperexternal surface of'the drag 2. Said detachable ears 9 are provided withperforations or apertures 10 through which belts or screws or rivets maybe inserted for securing said ears to the ends 11 of the drag 2. Theears 9 are provided with a'rectangular depression 12 for the purposemore fully hereinafter described.

In Fig. 4 I have shown a detachable clamping mechanism which is mountedon the ears 9. Said clamping device consists of a plate 13, the samebeing mounted on a tapering stud 14:, the said tapering stud provided atits opposite end with a screw threaded portion 15, the same adapted toreceive a nut 16.

Mounted on said screw threaded portion 15 is a detachable plate 17.

When the clamping device is in use the horizontal portion 18 of the ears9 is located between these two plates andmay be clamped therein by theagency of the nut mounted on the screw threaded portion 15. When thesaid clamping device is in use the screw threaded portion 15 is locatedin a rectangular depression 12, and as said rectangular depression 12 isconsiderably larger in dimensions than thesaid screw threaded portion itcan be readily perceived that the said screw threaded portion may beadjusted within said In other words the clamping device as illustratedin Fig. 4; is detachable from and also adjustable on the ears 9.

When the clamping device is in use the tapering'portion of the stud 1 1is located in the U-shaped depression 7 of the ears 4, and when solocated the cope 1 may be readily applied or placed upon and removedfrom the drag 2 without in any manner affecting the clamping device.

It can be readily seen from the above description, that by theemployment of my con- 2. Aflask clamp consisting of a detachable earprovided with a U-shaped depression and strengthening ribs, a detachable ear provided with a rectangular depression, a plate carry ing atapering stud provided with a screw threaded portion, a detachable plateand a nut, substantially as set forth.

In testimony whereof Iaffix my signature in presence of two Witnesses.

HENRY J. GRAB.
